Needle Felting: Samus Aran

Samus is 100% needle-felted wool. For those unfamiliar with the technique: wool roving (the stuff yarn is spun from) is stabbed over and over with a very sharp barbed needle to make it dense.

You have to keep going over areas in a sometimes-painful, time-consuming process that is a lot of fun.

...A lot like playing Super Metroid, actually.
